Specification of Letters Patent.

Patented Apr. 24, 1917.

Application filed June 21, 1916. Serial No. 104,860.

To all whom it mag/concern:

Be it known that l, .\.BIL\IIA1['DEUTSCII- msrnn, a citizen of theUnited States, and a resident of New York city, in the county of New.York and State of New York, have in ented certain new and usefulImprovements in Envelops, of which the following is a specification.

This invention relates to mailing envclops, particularly of the typeadapted for use in' mailing matter at third class maiimatter rates.

One object of the invention is to provide an envelop of this characterin which the contents is securely held.

Another ob ect is to provide an envelop of this character which has theappearance of a sealed envelop and yet can be readily opened forinspecting the contents as required for third class mail matter.

A further object is to provide an envelop which may be made up at smallcost and is readily manipulated.

The various further objects and advantages will more fully appear fromthe detailed description and the features of novelty'will beparticularly pointed out in the claims.

In the drawings illustrating the invention,

Figure l is a development of the blank from which the envelop is formed.

Fig. 2 is a perspective View of the envelop showing the manner in whichit is folded and assembled.

Fig. is a rear view assembled.

Fig. 4c is a face view in-perspective illustrating the manner in whichthe slot' is opened to insert or remove the contents.

Fig. 5 is a face view of the envelop as sealed for mailing.

Fig. 6 is a similar view of a modified form with a straight instead ofcurved slot.

Fig. 7 is a development of a blank illustrating a further modified form.

Fig. 8 is a rear view of the assen'ibled envelop made up from the blankillustrated in Referring in detail to the (.lIZLWll'lg, par ticularly toFigs. 1 t0 5, the envelop is formed with the face portion 10 and backportion 11 and the gummcd flaps 19., 13 and 14 formed preferably on theface portion to unite the same with the back portion. Formed in the faceportion 10, adjacent to of the envelop as entirely free and one endthereof, is a slot 15 of preferably curved contour, and from theadjacent end of the back portion 11 extendsa flap 16 which is tuckedinto the interior of the envelop when the flap 12 is pasted over theback portion, as clearly appears from Figs. 2 and 4.

When the envelop is made up, the flap 16 is concealed in the interior ofthe envelop and serves the function of retaining the con tents wheninserted in the envelop. Thus, when it is desired to insert the matterin the envelop, pressure is applied to the longitudinal edges 17, 18,(Fig. 4), opening the slot 15. The matter may be then readily insertedthrough the slot and the concealed flap l6 folded ther'eovcr in theinterior of the envelop. If desired, cealed flap 16 may be slot, forminga lock for contents.

I prefer to use a curved son that the envelop may opened. However, ifdesired, a straight slot 15 may be used as shown in Fig. 6.

In the modified form illustrated in Figs. 7 and 8, the slot 15 isdisposed in the back portion '11 and the flap 16 is folded back onitself at the interior of the envelop adapted to pass through the slot15 as in the other form described. The gnmmed flap 12 is preferablyprovided with the extensions 12 at the extremities thereof formingreinforcements for the end of the slot 15, thus preventing the tearingof the paper. In this construction, the face portion 10 is left smoothfor the addressing.

It will thus be seen that I have provided an envelop which may be usedfor sending mail at third class mail rates and, at the same time, thecontents is securely held in the envelop and may be readily inserted andremoved. The envelop is inexpensive to make and efiicicnt in use.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. An envelop comprising a face portion and a back portion, a slotformed inone of said portions, and a normally concealed flap freelydisposed at the interior of the envelop opposite said slot, whereby thematter may be inserted into the envelop and retained by the concealedflap.

An envelopcomprising and a back portion, a slot formed in one of passedthrough the securely holdingthe slot for the reabe more readilymoreover, the con- .110 a face portion the interior of the envelop fromone of the lateral edges of one of said portions, there being a slotformed in one of said portions in juxtaposition with said flap, gummedflaps on the edges of said portions sealing the edges of the envelopabout the entire perimeter of the same, said first mentioned flap beingof a size to pass frointhe interior of the envelop through the slot soas to lock the contents of the envelop within the same.

4:. An envelop comprising a face portion, a back portion, gumrncd flapsextending from the edges of the face portion, a flap extending freelyfrom one of the edges of the back portion within the envelop andnormally concealed therein, said back portion being formed with a slotadjacent said flap through which slot the flap may .pass to the exteriorof the envelop to lock the contentsv of the envelop within the same.

5. An envelop comprising a face portion, a back portion, gummed flapsextending from the edges of the face portion to seal the envelop aboutits perimeter, a flap extending from one of the edges -of the backportion .slot being formed with portions passing across the ends of theslot to reinforce the material thereabout.
